CAMDEN -- The Betsy Ross Bridge is in line to become the first span in the Philadelphia area with express E-ZPass lanes.

The Delaware River Post Authority on Wednesday approved spending about $350,000 to design the lanes on the bridge that connects Philadelphia and Pennsauken. Drivers would be able to go 45 mph while their transponders pay their tolls.

The system could be ready for traffic in about a year.

The bridge is the newest and least-used of the four connecting Pennsylvania and New Jersey in the Philadelphia area.

The DRPA says the Commodore Barry Bridge may soon get the express lanes, too. But it's more complicated for the bigger Ben Franklin and Walt Whitman bridges because of the design of approaches and exits.
